Many years ago before Equestria or all the creatures that live in it, they were creatures that protect a Prism of Light that bathe the world with all the good that came with it. But whenever there is light, darkness and shadows will always form. A war between light and darkness broke out and the celestials had no choice but to seal away the darkness as they sacrifice their lives to save their land.

Many years later, after Cozy Glow almost sucked away all the magic in Equestria, she unknowingly weakened the seal and the great Darkness has risen once again. Luckily, the Prism of Light had conserve the Celestials souls and placed them in small Mechanical Animals and placed their powers within geos and they have chosen Champions to defend Equestria from the darkness.

(When they transform, they'll be wearing what's on the image cover. And the yellow ranger is a guy while the green ranger is a female.)
